ABSTRACT
Introduction: the close relationship between endodontics and periodontics is firmly established. Many authors claimed that pulpal inflammation might occur following periodontal diseases. The purpose of this study was histological evaluation of pulp in teeth with periodontitis
Materials and Methods: 32 single root teeth with periodontal diseases and without any caries and restoration selected for extraction were used in this study. Extractions were done after special clinical and radiographical examination. Samples were fixed in 10% formalin and then decalcified by EDTA for three months. Six micron sections were prepared and stained by H and E. Pulp status was evaluated histologically under light microscope
Results: showed that the amount of inflammatory cells was directly related with mobility and pocked depth. Atrophy in pulpal vessels as well as calcific feature were found in samples with deeper pocket
Conclusion: the findings imply that pulp is significantly affected by periodontal diseases. This should be a carefully considered factor when dental treatment is planned
